https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231457 --- Comment #12 from dimka@dz.dn.ua --- I check and made sure that 12.0-RELEASE/amd64 is also affected by this prob= lem, test tool and sendmail processes was killed by OOM after physical memory is over and several megabytes of swap were used. Short hardware details: CPU: Intel(R) Celeron(R) CPU 847 @ 1.10GHz (1097.53-MHz K8-class CPU) real memory =3D 2147483648 (2048 MB) avail memory =3D 1987403776 (1895 MB) FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs FreeBSD/SMP: 1 package(s) x 2 core(s) da0: <SanDisk Ultra USB 3.0 1.00> Removable Direct Access SPC-4 SCSI device da0: 14663MB (30031250 512 byte sectors) You can a very simple test on your hardware or VM: 1. Install system from DVD to cleaned drive in "Auto (ZFS)" mode. 2. Comment GPT swap entry (created by installer) in /etc/fstab. 3. Create swap space on ZFS pool: # zfs create -V 8GB -o org.freebsd:swap=3Don zroot/swap 4. Reboot. 5. Compile and use "Memory occupation test tool" from bug report attachment= s: # ./memphage 9500 Argument is memory occupation limit (mem free + swap free - 500) in megabyt= es. --=20 You are receiving this mail because: You are the assignee for the bug.=
